Why FlashGot detects nonexist download managers?

[instanton]

I updated my browser on Mac to firefox4 today and found myself have to use flashgot in order to work with a download manager. The strange thing is that FlashGot detects automatically Speed Download Lite as an available download manager. I remember that I once tested Speed Download Lite but then deleted it with AppZapper almost 3 years ago. So I am pretty sure that Speed Download Lite is Not available as a download manager on my system. The question is where does FlashGot find any traces of Speed Download Lite?

Because they're there
Looks like AppZapper wasn't enough (you probably should have used Speed Download's own uninstaller, if provided).
